IS BIG BANG TRUE OR NOT?

Big Bang is something like a “Bang” which means to explode which is true. Big Bang concept was first given by Fred Hoyle English Astronomer. He gave the concept of “steady State” model to represent the Big Bang model. Big Bang can be measured with the structure of the universe and some observations. Vesto Splipher in 1912 from the Doppler Shift (Note: Doppler Shift is given by Austrian Physicist Christian Doppler, in his effect he said universe is expanding as galaxies are receding from us by his two shifts red shift and blue shift. In red shift, an observer looking at galaxies are moving away from us and has longer wavelength, where as in blue shift an observer looking at galaxies are reaching towards this and hence has shorter wavelength. He gave the Doppler Effect concept in 1842) noticed a case of spiral nebulas (which is the obsolete from of spiral galaxy). He also notices that spiral nebulas are receding from us. Russian Mathematician and Cosmologist Alexandra Friedman from the Albert Einstein’s equation of general relativity said that universe is expanding and is not “static universe” as said by Albert Einstein ( when Albert Einstein said this statement Static universe or Cosmological Constant, he said this is a greatest blunder of my life). After then Edwin Hubble American Astronomer in 1924 also said that galaxies are moving away from us which means universe is expanding. Belgian physicist and Roman Catholic Priest George Lemaitre said that recession of the nebula explains the expansion of the universe. He said mass of the universe came into existence from a “primeval atom” when the fabric of space and time came into existence.

However, Big Bang started with three elements “Lithium”, “Hydrogen” and Helium”. But, why these two elements are necessary for Big Bang? Why Big Bang occurred? These questions are too complicated that we cannot give their answers. There is lot of problems related to expansion of the universe such as “Dark Energy”, “Horizon” and “Big Rip” and many others. When we talk about horizon problem we are not sure whether universe has its boundary or not. Astronomer Sir Arthur Eddington said “the boundary condition of the universe is that it has no boundary”. We have Wilkinson Microwave Anisotropy Probe Satellite which shows the almost the edge of the universe but not confirms the exact boundary. There is another problem which universe face is “Heath Death” which means when the universe reaches its thermodynamic equilibrium in other words maximum entropy then the there is no difference between temperature and universe will have no longer process to perform any work. In simple form, when the temperature will be same everywhere in universe this will cause a heath death of the universe which means there is no transfer of heat whether in mechanical, electrical or any other then it is said to be a dead heat and ultimately heath death of the universe. When the universe has an enough matter density to contract itself back then it will eventually shrinks in a small point (singularity) then the temperature at this point rises then give birth to a “Big Crunch).

The term “Heath Death” first coined by William Thompson (Lord Kelvin) in 1850’s. He also said that heat is not a substance but a dynamic form of mechanical effect. The fate of the universe also depends on “Critical Density”. We have another kind of state where universe cools and reaches its state of entropy also known as “Big Freeze” (density of universe is less the critical density) which will give birth to a new Big Bang. Singularity which means universe was expanding from a single small point of hole which is infinitely dense and curve, from this singularity where Big Bang occurred. But what exist beyond Big Bang if we say that it had its beginning in past? Is there anything beyond Big Bang when it happened? Why we say singularity exist with infinite dense matter and radiations into it? Which seems there is nothing beyond Big Bang? There are many reasons as we say that universe has its beginning but not forever, as it started from something complex engineering where selected matters and radiations are compel to contain in it (universe).  There existed something beyond universe which is our beyond of our laws and principles “where we find this, this is only a complex form of beginning”.
